I needed an indoor HF antenna recently and had a 40 ft roll of Radio Shack
twinlead. I cut down the middle about 16.5 feet, hung one end at one side
of the room and the other end at the other side of the room and fed it into
the balanced line input on my tuner. It tunes easily. I have no ground set
up, so I ran another 16.5 foot wire from the ground port. Making contacts
is a bit of a struggle, from my QTH in Michigan I've worked Nevada and
Arizona on PSK and during the DX contest today in limited operation near
sunset I worked Barbados and the Dominican Republic with about 50W
(probably a bit of a high level of RF radiation, I know). The question I
have is what the downside of this is. I have seen many websites that show
various antennas fed with twinlead, but I've never seen my approach (the
twinlead used for both the antenna and feedline). Since I got this roll of
twinlead on clearance from Radio Shack for 38 cents, this is a cheap
antenna indeed.

Paul,
Should work fine on the higher frequencies. But it may have limited utility
on 160, 80, and 40
since it is only about 10 meters long. I assume your contacts were on 20
meters. where your
balanced line might be near 72 ohms.

If it is truly balanced you should not need a ground. Assuming
that the high RF in your room does not bother your rig/setup and assuming
that no one gets burned
by coming in contact with the antenna while you are operating, you should be
ok.
